Graphical Issues

by Superflyguy3 / September 28, 2014 3:45 AM PDT

Need some help here, I built my own PC about a year ago and all was good at the beginning, it cost me about £1,200 and the hardware far surpasses the recommended hardware for any of the games I play.

Hardware:
Radeon R9 280x Msi Graphics card
16Gb of RAM
Excellent Screen
etc.

However a problem that is beginning to get worse and worse are these really odd pixelated squares that seem to crop up on a more and more frequent occasion. They seem to also react to me typing or moving the mouse as they flicker and it seems the patch of screen that one square covers, appears onto the other square. If anyone can give any advice whatsoever, if its maybe a hardware issue, or if it could be a fault in me building the computer. Sadly whenever I Print Screen, the cubes dont appear on the pasted image.

I'd try another monitor first (that's free if you know somebody with a monitor you can use for an hour or so), then another graphic card. If none of the two help, post again.

I'd actually start with a new cable first, then move on to a new monitor. That it doesn't show up on screen captures points to it either being a bad cable or bad monitor. We don't know if we're dealing with a VGA, DVI, HDMI or even DisplayPort cable here, but even with digital setups like DVI there is still a small margin of error for things like this.

(NT) That makes a lot of sense.

HDMI

It uses an HDMI cable, a friend of mine tells me that my hardware could even be almost 'over-killing' games im currently playing and even suggested perhaps under-clocking my CPU or GPU, does this sound like a viable source of the graphical errors too?

In your BIOS

set it to assign an IRQ to the mouse if the setting is there. If there's a setting for setting an IRQ to the VGA, then do that also. This will help assure they aren't using a software "IRQ sharing".

That was phased out

That was phased out with the demise of the ISA bus; everything from the PCI bus and later have automatic IRQ management. If we were talking about an old 486 or maybe even Pentium system, sure, but something built within the last year, give or take?

Plus if it were that, you'd expect the image in the video buffer to be corrupted and show up in a screen capture. So my money is still on a bad cable, especially if we're talking VGA. I had to replace one on a monitor at work because every morning I'd come in and it would look like a 3D image without the glasses. No matter how much adjusting I did I could never get rid of the image smearing completely. If you have better than average peripheral vision, it'll do a number on you over the course of a day. So while not the same as the OP's symptoms, they are still rather similar in nature.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
